Hello, I can not decide to buy which brand valves, so I want feedback from who used which brand for how much milage?
Options are Supertech black ntiride, Ferrea 6000 and GSC power division valves.

Thanks.

 

Ferrea. They are the standard for racing valves. Valves are only made by a few companies so Supertech and Gsc are great products but prob made from one of the same makers as Ferrea. I have Ferrea sodium filled valves on my evo and I have maybe 5k on them with no issues what so ever on them.

 

Thank you for feedback. Are ferrea 6000 valves sodium filled ?

 

Not a problem glad I can give you some feedback. No they are not. The sodium filled ones I believe are just the race valves.

 

Ferrea or GSC or excellent options I wouldn't run supertech.

FWIW, HeadGames used Ferrea comp plus valves in my race package head. But I don't think you can go wrong between Ferrea or GSC.

 

GSC in my evo

Ferrea in my supra...

personally...for an evo, i would go GSC...
